目的分析彩色多普勒超声与CT诊断急性胰腺炎(acute pancreatitis,AP)的价值。方法选择2013年1月—2014年6月收治的AP患者112例,均行彩超与CT诊断,分析胰腺检出率及在彩超与CT下的影响学表现。计数资料采用χ2检验,P<0.05为差异有统计学意义。结果彩色超声与CT检出轻型AP检出率分别为65.7%、88.6%,比较差异有统计学意义(χ2=10.370,P<0.05);彩色超声与CT检出重型AP检出率分别为95.2%、100.0%,比较差异无统计学意义(χ2=0.512,P>0.05)。超声小灶液区、胰腺局限性增大、胰管扩张、胆总管结石检出率分别为10.7%、12.5%、25.0%、12.5%,CT分别为26.8%、28.6%、10.7%、1.8%,比较差异均有统计学意义(χ2=9.495、8.864、7.791、9.692,均P<0.05)。结论 AP在彩超下可见胰管扩张、胆总管结石;CT诊断胰腺局限性增大、内部小灶液区检出率更高。在重型AP诊断中两种检测方法无显著性差异,轻型AP诊断中,CT检出率高于彩色超声。
Objective To analyze the value of color Doppler ultrasonography and CT in the diagnosis of acute pancreatitis (AP). Methods One hundred and twelve patients with AP who were admitted between January 2013 and June 2014 were diagnosed by color Doppler ultrasound and computed tomography (CT). The detection rate of pancreas and its effect under color Doppler and CT were analyzed. Count data using χ2 test, P <0.05 for the difference was statistically significant. Results The detection rates of light AP with color ultrasound and CT were 65.7% and 88.6%, respectively, with significant difference (χ2 = 10.370, P <0.05). The detection rates of color Doppler ultrasound and CT were 95.2% %, 100.0% respectively, with no significant difference (χ2 = 0.512, P> 0.05). Ultrasound in the lesion area, pancreatic enlargement, pancreatic duct dilatation, common bile duct stones were 10.7%, 12.5%, 25.0%, 12.5%, CT were 26.8%, 28.6%, 10.7%, 1.8% The difference was statistically significant (χ2 = 9.495,8.864,7.791,9.692, all P <0.05). Conclusions The pancreatic duct dilatation and choledocholithiasis can be seen in AP under color Doppler ultrasonography. The limitations of CT in diagnosing pancreatic pancreas increase, and the detection rate of internal microfocal fluid area is higher. In the diagnosis of heavy AP, there was no significant difference between the two detection methods. In the diagnosis of light AP, the detection rate of CT was higher than color ultrasound.
